| Abstract: | An organic-inorganic complex mono-CeIVsubstituted sandwich-type phosphotungstate（H2dap）2]2.5H5Ce（α-PW11O39）2].11.5H2O（1;dap=1,2-diaminopropane）was prepared under hydrothermal conditions.The structure of as-synthesized product was characterized by means of elemental analysis,infrared spectrometry and single-crystal X-ray diffraction.Resultsindicate that 1 crystallizes in the triclinic P-1space group with a =1.254 9（7）nm,b =1.915 9（11）nm,c=2.129 0（12）nm,α=68.426（10）°,β=88.320（10）°,γ=89.853（10）°,V =4.758（5）nm3,Z=2,Dc=4.116g/cm3,GOOF =1.022,R1=0.111 2,and wR2=0.218 9.Besides,the molecule of 1 is composed of 1crystallographically independentmono-CeIV substituted sandwich-typeCe（α-PW11O39）2]10-polyoxoanion,2.5discrete diproto-nated H2dap]2＋ cations,5protons and 11.5lattice water molecules. |
